Speciiicntioir forming part of Letters Patent No. 54,346, dated May 1, 1866.

To all rwhom Iit may roneern: x

Beit known that I, EDWIN H. HILL, of the citjY and county of W'orcestcr, and Commonwealth of Massachusetts,have invented a certain new and useful Improvement in the Mode of Making Pipes for \Vater, Steam, and other Purposes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming apart of this specitiention, in which- Figure l represents a perspective View of a section or piece of pipe made according to my invention. Fig. 2 represents a perspective view of a section of pipe made according to my invention, having a coupling attached to one end thereof; and'Fig. 3 represents a longitudinal central section of two pieces ot' pipe connected by a coupling-piece.

In the drawings, A represents the pipe, and B the coupling-piece. The pipe is made as follows: I take wire and coil it upon amandrel of the desired size for the bore of the pipe, after which t-he coiled-wire pipeis dipped Vor immersed in melted tin or other suitable nou-corrosive metal, whereby the coils a of the wire are not? only completely coated over `with the melted metal, but are atthe same time secure-,l5Y united together, as indicated in the drawings, in which a. represents the wire, and b the tin-coating.

B represents the coupling, which is made in the same Way as the pipe, and then soldered to the ends of the pipes, making a simple and tight joint.

Round, dat, or other shaped wire may be used in the construction of the pipe. The pipe thus made is both strong and non-corrosive, thus obviar-ing many ot' the objections -to the use ot' lead und iron pipes.

H avin g described myinvention, what Iclaim ent, as an improved article ot' manufacture, is v A pipe for water, steam, and other purposes, made as described, and shown in the accompanying drawings.
